<br />The storm sewer instE,llations are at three locations along Olel GoldEm Road <br />as shown on Figure 1\'-1. The pipes at Locations land 2 were historically <br />existing and were enlarged and inlets constructed. l,ocation 3 at Quaker Street <br />'.Jas installed to pick up flc,,-,! in the road \-1hich \.,a8 missed by the inlets at <br />Locations 1 anG. 2. The road capacity is 10'H due to th,2. street grade varying <br />beth'een -.1% and -.42 along Old Golden Road and excess runoff yJill flow to the <br />North over the 6-1nc1-:_ curb. Thus, by controll:ing the runoff from the pipes, <br />any damage which occurs to the houses along Old Golden Road can be minimized. <br /> <br />The installation of curb and glltter along both sides of Old Golden Road will <br />carry most of the rur.off from minor storms directly dm-m to Lena Glllch. <br /> <br />The hydrologic computations for the area which contributes historically to the <br />Hest side of Quaker Street at the drainage-,.my are giv,en in Tables IV-2 thru 5. <br /> <br />The 2-year storm runcff rate is computed to be 24 cfs. The hydra.ulic capacity <br />of the existing 36" CSP under Quaker Street at 12th Place is 25 cfs. By <br />improving the inlet conditions of the pipe, the pipe capacity could be increased. <br />This would result in additional runoff contributing to the drainage-"ay East <br />of Quaker Street. The residents "auld not approve of this and have stated so <br />verbally due to existing. channel conditions dm.mstream of Quaker Street. <br /> <br />/8 <br />
